“In the last decade, a growing number of colleges and universities have been asking students to identify their gender identity and sexual orientation on admissions forms, either by adding a question to their own application or by adding a supplemental question to the Common Application. These institutions include Dartmouth College, Duke University, Elmhurst College, Elon University, Massachusetts Institute of Technology, Northeastern Illinois University, The Ohio State University, Purdue University, University of Iowa, University of Maryland, University of Rochester, and all two-year colleges in California and Washington. In addition, the Cooperative Institutional Research Program (CIRP), the most comprehensive source of information on college students, has also begun to ask questions about sexual orientation and gender identity.”
